Abstract

The application relates to the technical field of handrail rails, in particular to a handrail rail for high-rise emergency escape, which comprises a rail and universal wheels, wherein a separation mechanism is arranged on the rail and comprises a fixed shaft, a torsion spring and a dust shielding plate, the bottom of the dust shielding plate is clamped with the torsion spring, and the bottom of the dust shielding plate is rotationally connected with the fixed shaft. Through the setting of separating mechanism, the universal wheel separates two rows of dust shields with the division board and makes the universal wheel roll in the universal wheel groove, after the universal wheel passes through the dust shield, the torsional spring limit is located between dust shield and the track, the rebound force of torsional spring can make the dust shield cover again on the universal wheel groove to effectually prevent the entering of dust, piece, thereby avoided the barrier to block the stagnation that causes the universal wheel, also avoided the universal wheel to receive the jolt that the obstacle leads to simultaneously, make the universal wheel operation more smooth and easy, win the best escape time for the person of fleing.

Description

Armrest track for high-rise emergency escape Technical Field The application relates to the technical field of handrail rails, in particular to a handrail rail for high-rise emergency escape. Background The handrail is a circular pipe fitting or a cuboid-like piece arranged on the wall or the ground of the stairway, is used for being held when going up and down stairs, has the functions of supporting and guiding, is a common handrail, has the function of being held only when going up and down stairs, and cannot achieve the purpose of enabling personnel to escape quickly under the emergency of fire and earthquake. Through searching, chinese patent publication No. CN215387100U discloses a special handrail track for high-rise emergency escape, which belongs to the field of high-rise emergency escape. The handrail comprises a handrail body, a hanging structure and a track structure, wherein the handrail body is arranged in a stairwell and is used for being held when going up and down stairs, the hanging structure is arranged below the handrail body and is used for supporting the handrail body, the bottom of the hanging structure is bent to form a bent part, the track structure is arranged on one side of the bent part, the cross section of the track structure is rectangular and is used for sliding in a matched manner with a plurality of pulleys of special emergency escape equipment, the track structure is a pipe fitting or a cylinder, the surface of the track structure is integrally connected with the bent part, and anti-skid lines for decelerating are uniformly distributed at the bottom of the track structure.
